About this series

SS Tuffy Grade Miniature End Mills

Every .001″ is standard — and we'll hand-select any size in between.

RobbJack SS stub-length Tuffy Grade miniature end mills are stocked in EVERY .001" diameter from .005" to .062" as standard. Need a size in between? Under .062" we hand-select tools to any diameter to the nearest .0002" — a .0376" tool is a regular order, not a special. Ball-end (SS-2BN) and 4-flute (SS-4) variants are also offered. Customers report these tools run faster and longer than any others they have tried.

  • Every .001" diameter from .005" to .062" is standard, shipped from stock
  • Hand-selected to ANY diameter in .0002" steps under .062" (e.g. .0376")
  • 2 flute, square end, 30° helix, stub length for rigidity
  • Ball-end (SS-2BN) and 4-flute (SS-4) variants
  • Tight tolerances held in microns

Available uncoated and in TiN, TiCN, AlTiN, and Diamond-Like Carbon (DLC) coatings
